Moss is a flowerless plant that grows vigorously in shady and moist areas. They are found everywhere in the world, except in saltwater. They are generally 0.3 to 10 cm tall. However, some of its species are taller. They are so small in size that they are generally confused with fungus. However, they are actually plants.
Many homeowners see moss as a headache as it can damage the new roof and also removing moss can be a pain.
Some people think that moss is bad for your roof because they believe it will grow indefinitely. There are a few good reasons to remove moss from your roof, but this is not one of them.

It’s better than green algae under a roof, though, which could actually eat away at shingles and create all sorts of problems! It’s also better than dirt accumulating under your roof, which would eventually lead to poor drainage (causing mold) as well as pest infestations.

There are many misconceptions about moss. So, in this article, we aim to clear those misconceptions and discuss whether moss is beneficial or harmful for your roof and whether you should remove the moss or not.
Let’s delve further and find out!
Is Moss Bad For My Roof?
Mosses are widely found in roofs of almost all countries in Europe and the USA. There would be hardly a roof in the aforementioned areas with no moss. Honestly, moss in a controlled proportion looks attractive and makes your home look charming. So is moss really bad for your roof and whether you should kill the moss through pressure washing or a professional moss removal service to protect your roof?
Well, the simple answer is yes. Let’s discuss how it is harmful to your roof.
As mentioned earlier, moss grows in shady and moisture areas. If your house is situated in one of those areas where the atmosphere is generally favorable for its growth, it is very likely to grow on your roof. Of course, no homeowner wants to see his roof covered with moss or likes to see moss covered roof.
Here is how moss can cause damage to your roof:
Moss Growth Causes Leaks
The most obvious drawback of mosses on your roof is that they may cause leaks. When moss grows on your roof, it pushes underneath tiles, shingles, and other roof materials. As a result, tiles and shingles are pushed up and uprooted from the roof surface. All of this results in immense damage, often in the form of holes and leakages.
To make things worse, when you try to eliminate dead moss from your roof, tiles, and shingles will be pushed back in a weird way leading to further structural degradation. To put things briefly, they can be a recipe for disaster for a roof.
Roof Moss Puts More Weight on Your Roof
Another reason why you should never let mosses grow on your roof is that it puts a lot of unwanted weight on your roof. Mosses retain a big amount of water. It goes without saying that if there is a lot of moss on your roof, it will put extra hundreds of pounds of weight on your roof. Your roof is not designed to support that much unwanted extra weight.
Hence, it’s not good for your roof’s health and the life of the roof reduces.

If there is a tree that causes shade on your roof, prune some of its branches so that there is no shade on your roof. Sunlight is your friend and helps you get rid of mosses naturally.
